Interview a little two informal, they did most the talking and were trying to sell me the job rather than trying to get me to convince them.
They also didnt mention until AFTER offering me the job that I wouldnt actually be their employee, but a 'independant sales rep', which means I would be technically self employed, unsalaried and get no security (e.g. no sick leave, no holiday pay, be responsible for paying my own taxes)
If you havent worked it out by now -its basically a scam!
